Abstract
We have searched for the flavor changing neutral current decay D0 → μ+μ− in the dimuon data obtained by the E771 experiment conducted at Fermilab. No evidence is found. A 90% confidence level upper limit of 4.2 × 10−6 is obtained for the branching ratio. This new upper limit is about two times lower than the best published result. © 1996 The American Physical Society.File in questo prodotto:
